would just like to put an idea out there.. get some feedback. i have a small inverter plasma cutter.. it can handle about1/4" if i take it slow.
was thinking it would make an interesting project to make an X-Y cross slide type table.. and make a holder for the gun. two small motors and another set of wires for the trigger and i might have a little CNC cutter. maybe just something to cut nice clean circles out of sheetmetal for now.
even just the torch on a linear slide would be nice for making straight consistent cuts.
i wouldn't want to permanently modify the plasma cutter.
only problem i forsee is ensuring that the torch is cutting. sometimes when cutting freehand i have to push the button again (it has some lag) to get it restarted.
